The periarticular fractures of tibia are usually managed nonoperatively using cast immobilization. But considerably displaced or markedly unstable fractures are difficult to maintain the reduction. Malunion and many other complications including joint stiffness are common, particularly after lengthy immobilization. Currently, operative treatment with rigid internal fixation is attempted and so early joint motion will be possible. But if there is open fracture with injury of soft tissue, the choice of treatment is limited. We managed 6 cases of periarticular fractures using Ilizarov external fixator from June, 1990 to June, 1991, the following results are obtained; l. All of 6 cases were open fractures, of which type I was 1, type II was 1, type III was 4 cases and 2 cases were associated with severe infection. 2. Of 6 cases, fracture of the proximal tibia was 4 cases and those of the distal tibia were 2 cases. 3. 5 cases had full range of motion, but 1 case showed partial ankylosis due to fibrosis between of proximal tibia and distal femur. 4. Skin graft was done in 4 cases. 5. 2 cases were treated with internal fixation with plate and screws due to delayed union and infected nonunion. 6. Time from injury to placement of Ilizarov device was ranged from 1 day to 57 days except transferred patient. 7. Time spent in the apparatus averaged 3.7 months, and ranged from 7 weeks to 6 months. 8. All patients were placed in a cast after removal of the device.
